Hello World,
I have 6 hosts where VMs for Jenkins are located. The VMs are all
QEMU/KVM and are handled by libvirt. After a Jenkins update I cannot
connect to 2 of these 6 hosts any longer.
Hosts: (all) Debian GNU/Linux 10.3
Jenkins: 2.222.3
Libvirt plugin: 1.8.5
I have a user "jenkins" on the Jenkins server and on the host with the
virtual machines. I copied the keys from Jenkins to the host and can ssh
from Jenkins to the host without password.
I can also (with the user jenkins) connect to qemu+ssh://<host>/system
within the virtual shell virsh and perform commands.
But if I try to connect from Jenkins (in the Clouds Settings) I get the
error message:
com.nirima.libvirt.xdr.XDRException: authentication required
if the "Use Native Java libvirt client" is set.
And also on the host, I have the following entry in the log (syslog and
debug):
May 25 10:59:59 aat-1 libvirtd[986]: authentication required
But in the auth.log, I get:
May 25 10:59:59 aat-1 sshd[10878]: Accepted password for jenkins from
192.168.168.10 port 56746 ssh2
May 25 10:59:59 aat-1 sshd[10878]: pam_unix(sshd:session): session
opened for user jenkins by (uid=0)
May 25 10:59:59 aat-1 systemd-logind[501]: New session 341 of user jenkins.
May 25 10:59:59 aat-1 systemd: pam_unix(systemd-user:session): session
opened for user jenkins by (uid=0)
If "Use Native Java libvirt client" is not checked, I get an "ERROR"
link and if I click on it, a huge Java traceback is displayed, starting
with:
java.lang.NoClassDefFoundError: Could not initialize class
org.libvirt.Connect
at
hudson.plugins.libvirt.lib.libvirt.LibVirtConnectImpl.<init>(LibVirtConnectImpl.java:23)
at
hudson.plugins.libvirt.lib.ConnectionBuilder.build(ConnectionBuilder.java:97)
at
hudson.plugins.libvirt.Hypervisor$DescriptorImpl.doTestConnection(Hypervisor.java:454)
I noticed that the libvirt-slave plugin is compiled using Java 5. Is it
too old?
What can I do to solve my problem? Any ideas?
TIA and best regards
Andreas
